SIGNAL FOR FORCE-FEED LUBFHCATORS.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed March 27,1906. Serial No. 308.35 7.

To aZZ whom t may concern:

Be it known that I, JOSEPH HANsoN, a citizen of the United States, residing at 1nwood, in the county of Lyon and State of Iowa, have invented a new and useful Signal for Force-F eed Lubricators, of which the following is a specification. l

rl`his invention relates to attachments for force-feed lubricators, whereby a signal is sounded when the lubricant is exhausted, and has for its object to provide a simplyconstructed and easily-applied device of this character and to increase the efficiency and utility of the same.

With this and other objects in view, which will appear as the nature of the invention is better understood, the invention consistsin certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation.

ln the drawings, YFigure 1 is a side elevation of a force-feed-lubricator device with the improvements applied. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1. Fig. 3 is a sectional detail on the line 3 3 of Fig. 2. Fig. i is a detached detail of a portion of the tripping mechanism.

The improved device comprises a receptacle 10 for the lubricant, preferably cylindrical and provided with an internal plunger, (indicated by dotted lines at 11,) the receiver having a projection 12 at one end, through which the lubricant is forced and to which a suitable conductor is connected to convey the lubricant to any desired point; but as the conductor is not a part of the present invention it is not illustrated.

A threaded stem 13 extends into the receiver 10 and operates in the plunger 11, the stem extending at 14 beyond the casing and provided with a worin-gear 15 and a crankwheel 16, the latter designed to return the plunger to the rear end of the cylinder by hand when the cylinder'is to be recharged with the lubricant.

The lubricant'is supplied by a feed-conduit 17 having a controlling-valve 18.

l The cylinder 10 is supported upon a base 3 member 19 by a standard 20 21, and a U- shaped frame 22 ismounted to swing'frorn the standard 2O by pins or bolts 23 24, the frame 22 having a shaft 25 j ournaled therein and carrying a worin-pinion 26 for engagement with the worm-wheel 15 when the frame 22 is in one position and to be disconnected therefrom when the frame is released, as hereinafter described. The frame 22 is provided with a lip 27 or catch, withV which a rod 28 engages, the rod slidably disposed in bearings on the brackets 20 21. The rod 28 is upturned at one end and provided with a stem 29, extending through a stufiing-box 30 in the receiver 'l0 and adapted to be operated by the plunger 11 when the latter approaches the forward end of its'stro'ke.

The shaft is adapted to be continuously and intermittently rotated by a suitable connection with some constantly-moving portion of the machinery-for instance, with some moving part of an engine (not shown)- so that so long as the frame 22 is held in its upward position by the engagement of the rod 28 with its catch 27 the motion imparted to the shaft 25 will be transmitted through the pinion 26 and gear 15 to the stem 13, and thus force the plunger forwardly through the cylinder. The stem 29 is so located that when the plunger approaches the end of its outward stroke, or just before the lubricant is exhausted, the stem will be operated and the rod 28 moved endwise to release the frame 22 and permitting it to drop by gravity, thus disconnecting the worm 26 from the gear 15 and stopping the forward movement of the plunger and preventing damage to the device, which would othervvise result by the continued movementof the plunger.

The object of the present invention, about to be described, is to sound a signal or bell when the frame 22 is released and the forward movement of the plunger stopped.

The shaft 25 is provided with a ratchetwheel 31 and also provided with a collar 32, through which an arm 33 extends and supported adjtstably in the collar by a set-screw 34. The arm 33 is provided near theupper end with a bar 35, havingpawls 36 37, engaging the teeth of the ratchet-wheel 31 by grav ity.

upper end and is designed to be connected to The rod 38 is connected to the arm 33 at the a constantly-moving part oi the machinery, as above noted. Extending from the ratchetwheel 31 are a plurality of pins 39, spaced. apart at uniform distances and concentric to the shalt 25.

Pivotally mounted on the bracket 2() at 40 is a rod 41, having a gong 42 at one end and arranged with its other end extending in the path oi the pins 39, so that as the irame 32 is released and swings downwardly the pins will engage the rod and sound the gong. The anvil 43 is connected to the base 19 in position to`be engaged by the gong when the latter is operated, and thus sound the gong. A stop 44 is arranged to be engaged by the rod 41, preventing the gong Jirom bearing constantly upon its anvil 43, the resiliency of the rod 41 being utilized to sound the gong when the device is operated. By this arrangement when the 'frame 22 is held by the rod 28 in its upper position, or in position to cause the worm-pinion 26 to operate the worm-gear 15, the pins 39 will rotate over the shorter end oi the rod 41 and not produce any etl'ect thereon, the gong thus remaining inactive while the plunger 11 is being operated within the receiver. When, however, the frame 22 is released, as above described, the pins 39, moving downwardly with the trame, will-be disposed in position to act one at a time upon the shorter end of the rod 41, and thus intermittently elevate the gong and permit it to tall upon its anvil 43, and thus sound an alarm, the stop 44 preventing the gong l'rom resting upon the anvil, but utilizing the resiliency or the rod 41 to cause the gong to strike the anvil and then reb ound. rlhe operating-rod 3S being moved continuously keeps the shait 25 and its attachments constantly rotating, so that alter the frame 22 has been released the gong will continue to sound until the cylinder is recharged and the plunger again disposed in its rearward position and the iframe 22 adjusted in its upward or operative position, as will bev obvious. Thus the attendant will be noti'lied by the sounding of the gong oi the iact that the lubricating material is exhausted and requires replenishing. The device is simple in construction, can be inexpensively manufactured, and operates ellectively for the purpose described.

Having thus described the invention, what is claimed as new is- 1.
